Be it known that -I,- WILLfIAivI IRUBLr,- a citizen of the UnitedStates,-v anda resident of Tuckahoe, inthe county otWestchest'en and State of New `Kol-1Q have invented' certain new .andi useful Improvements in Grease-Cups, of which thepfollo'wing is a specification. p y y' k i Theinvention is a grease cup combining certain features .of yconstruction and rela-` tion y of a ,simple andractical character, enabling the greaseholderto Ibe removed, filled and replaced quickly and conveniently, causing it when inplace -to be securely held, and insuring cleanliness: VSince grease cups f are of necessity frequently placed in incon vcnient locations, the advantage offan organization wherebythe grease receptacle andplunger are removable by a `quick onehand movement, asin'the.- examples hereinafter described, will be readily appreciated.

able the barrel to be readily removed and preferably by only a partial turn, the screw connection is made of a quick-acting character, which may be accomplished as indicated in F 3 by the use of a multipleV thread, which on the barrel is confined to an upper region, Vleaving the lower part 'of' thebarrel plain as sho-wn at 7. It is imma-A terial whether the stationary shell. be thread ed throughout as in Fig. 2 or only at the top, as shown in Fig. 5. The removable barrel occupies a fixed position when in place, with its lower or inner edge bearing against a packing washer 8 at the bottomof the shell, this seat being the only limit to the inward movement of the barrel when the latter is inserted. The grease is delivered from time to time by means of a plunger 4carried by and adjustable in the barrel. In

Figs. 1, 2 and 4 this' plunger comprises a disk 9 of suitable material, secured to a screw-threaded spindle 10, which operates in an internal thread in a neckor nut member 11 united with the top of the barrel, the outer end of the spindle being provided with a handle 12. A compression spring 13 confined between the disk 9 and the top of the barrel takes up all looseness between the threads of the spindle and neck, in order that the adjustment of the plunger may not be disturbed as the result of vibration.

A rigid, spring-pressed locking member 14 is mounted on the removable grease-holding barrel 4, to cooperate with the locking formations on the stationary shell 1. for the purpose of preventing accidental unser-ewing of the quick-acting` connection between these parts. In the preferred form this locking member is arranged as a cap, having a top wall provided with a square opening, 15 for slidable reception of the neck 11, and a circular wall 16 surrounding the upper part of the barrel and formed on its lower or inner edge with ratchet teeth 17. A compression spring 18 interposed between the `top :wall of thecap and a collar l 19 on the neck 11, and housed by a flanged washer 20, urgesthe locking member inwardflso as to engageits teeth with those of the stationary shell.- The externally located locking member thus affords a hand grip,

being facilitated bythe presence of thel home the inclined sides of the ratchetteeth moved by a pull andv a twist, the locking member being grasped and moved outward to free the locking formations, and then turned, the latter movement causing .the barrel to turn also. By virtue o'l' thequickacting connection between the barrel andi shell,the separation in'ay be effected by a fractional turn, the whole operation of unlocking and taking off the barrel being performed without shifting the hand upon the grip, and by substantially a continuous manual movement. been removed-,the plunger Nis runl backfand theE barrel filled". The barrel lis then re'- in'serted in the shell and by a'turnequalto' that required for its removalseated irmly upon the gasket 8, the assembling operation plain portion or feirule 7, which serves to guide the entrance ofthe barrel intothe' shell and to assist the engagement of the threads. While the barrel' isbeing screwedi ride past each other idly, the spring-'1S yield? ing to the consequent movement of the lock-A ing member and insuring engagement of the teeth whenthefbarrel i'shon'ie, irrespective /Ofy variations inthe thickness of the washer. In order to enable the teeth to have fujll engagement with' each other at any point in the turning ofthe barrel when the latter' e'onies to rest against `thegasket,'th'e yop'enjf ingl is preferably made va little' large forl the neck l1, as ishownin Figui. :.so'thatrtliey locking member, while substantially nonrotary upon the barrel, as already stated, isstill capable of a slight relative turningl movement, suiiicient to enable its locking formations to takev properly into those of the shell when the assembling ofthe 'cup is completed. j

Fig. 6 illustrates as another form of quicle` acting screw connectionbetween the reniov'' able-barrel 4: and the stationary member la', al breech-block joint comprising screw threads 5a and 6at (not multipley threads)` interrupted by plain areas b'andQGb'." VVi'th this construction thev cupl is put together by entering the barrel intozthe shell in the relation shown in thek view until ittouches or nearly touches the conipressible gasket and then giving it -a slight turni, so' as to' engage the threaded areas and cause the barrel' edge to Ybe'f'crowd'e'd against thewvaslier: I-nr this way the barrel can be'removed and' replaced witha very short turning movejnient, but, nevertheless, when in assein'bled position is -securely held by the locking means. Both in this and in the preceding construction the quick-acting screwameans uniting the two parts of the cup is not relied -upon to form a grease-tight Joint. This is effectedinsteadby ythe pressure of the han barrel' is removed.

The ino'dificationlin Fig. 5 relates to the plunger. Here the spindle 10 is not threaded, and islheldvagainst longitudinal movei'nent in' its'bearingin the top of, the

barre'h' Its-lower part 10bis of square or' other appropriate cross-section, permitting the disk 9n,wh1eh isforined oi'y metal with av corresponding aperture in its centei,to

move longitudinally while compelled to turn with this shank portion. The edgej of the disk iscut Withscrewr threads, which ht threads 25 on: the inner face of the .bai-rel,

so thatfIt-he turning of the'd-isk causesit to inove" inward or 'outward,as"the ease may be., `The advantage f of this" arrangement is that the' spindleiandrrspindlehandle dov not have toiinove"lengtlifwiseyand thelack of space'is suchas to necessitate a ,teeth 3a maybe employedfthe' sidesof which slope in bothdirections, so that a turning movement is= all thati's'necessary toremove the barrel. -Inthisl'instance'the hand grip 2l? is shown as being .formed yon 'the periphery of 1a; disk lf9',' which, ylike "the collar 19 of the other views, is' unitedqwith the neck' flloff the removable grease-containing barrel. When the user Wishes totakefout the barrel, he' merely' grajsp'sA this hand-hold and turn'snitfpra part of a'revol'ution inthe unscrewing direction@ without pulling outward. v#Ii'i -this-'I-operation the oblique faces of the ratchet teeth ride over-eachotlier,j ther 1 loc'kingf inemberl 14a# ri'isiiig 1 and falling as-'thjey y'do"so".-
